293 Answer Y if you have a sound card based on the Ensoniq SoundScape
294 chipset. Such cards are being manufactured at least by Ensoniq, Spea
295 and Reveal (Reveal makes also other cards).
296
297 If you compile the driver into the kernel, you have to add
298 "sscape=<io>,<irq>,<dma>,<mpuio>,<mpuirq>" to the kernel command
